Obesity is defined by a BMI above 30.0, and overweight rates are represented by a BMI between 25-29.9. Obesity is more generally described as a dietary disorder where the body has an excessive amount of body fat. According to the U.S. Centers for Disease Control and Prevention, obesity reduces quality of life and life expectancy by increasing the risk of chronic diseases such as hypertension (high blood pressure), type 2 diabetes, coronary disease, stroke, and osteoarthritis. In recent years, obesity rates have been skyrocketing, affecting an estimated 40% of U.S. adults.
